The present invention relates to a home simulation and construction management method for providing a client with various information for home design, purchase, and new construction on a computer network such as the Internet, and automatically simulating on the Internet with a client designed design.

In general, a user needs to go through a process of planning, planning, designing, engineering, construction, maintenance, and repair as shown in FIG. 1A to newly construct or purchase a house. Many companies are involved in this home buying process, and there is a great deal of information exchanged between them. In other words, the construction of a house requires a designer, a material company, and a contractor. The designer takes charge of sales, construction and structural design, licensing, and supervision, and the material company takes care of public relations, sales, manufacturing, and delivery. In addition, the contractor is in charge of public relations and sales, and when architectural design is obtained from the designer, he is responsible for structural design, manufacturing, management, and construction.

Figure 1b schematically shows the ordering and contracting process of a conventional steel house. In the housing commissioning stage, there are few examples of attracting customers by using a model house, and the housing commissioner is made in such a way that the builder approaches the customer through exhibitions or advertisements or relies on the introduction of others. When the client approaches, the client hears the requirements for price, scale, space composition, construction, etc., suggests a close plan, then finishes the plan in a way that partially converges the design, and does not have a floor plan close to the requirements. In this case, continue with the customer and create a new floor plan. When the floor plan is completed, a full-scale basic design for construction is undertaken, and a construction drawing, a structural drawing, an electrical wiring diagram, a mechanical design drawing, and the like are produced, and in some cases, a miniature model is produced or a perspective view is created. If the land is in an urban planning area, the building report or permission must be obtained according to the law. Once the basic design is completed, the necessary materials are purchased and the subcontractors involved in the construction are selected. The subcontractor writes their own shop drawing, and sometimes other design changes are required. After the building is completed, the landlord or subcontractor will repair the defect for a fixed period.

In summary, the problems encountered in this process are as follows.

As discussed above, the type of business negotiations face-to-face is a limiting factor in the market, and it is necessary to feel the spatial concept by imagination without omitting high-cost perspectives, and the cost of construction increases due to frequent design changes. The cost of construction will rise due to the re-contracting and re-contracting, and the owners will have less opportunity to participate directly in the project, causing frequent problems in construction and lack of customer's confidence in quality and price.

Therefore, in the steel house building industry, it is necessary to establish a system in which the owners can participate in the decision making and sufficiently reflect the demands. In addition, not only provide engineering for the structure of the steel house but also a total system that enables the steel house's architectural design, interior, construction management, maintenance after construction.

An object of the present invention for solving the problems of the prior art as described above, the owner is provided with a simulation service for designing the building on the web, so that the user can simulate the desired house, select a construction company and manage the construction process To provide a method of building simulation and construction management using the Internet.

Another object of the present invention is to provide a Web-based Architectural Simulation System for Steelhouse (WASS), which allows the execution and evaluation of the project from the project planning stage to the virtual space based on the Internet and intranet. The goal is to enable decision making and to build an interactive database of informational information that occurs throughout the process to efficiently share and update data.
